针对2012‐04—07甲子以东海域3个站的潮位和海流连续观测资料，采用潮汐和潮流调和分析、海流旋转功率谱等方法，研究了它们的潮汐和各层潮流的分布特征，探讨了这些特征形成的原因。结果表明：1）甲子港及其以东40 km海域典型日潮的形成是由于M2分潮的无潮点的存在和潮能在甲子外海的辐散两种原因引起的；2）日潮海域的潮流则是正规半日潮流的性质；3）研究海域的潮波较为复杂，驻波性质不明显，前进波性质较为突出；4）通过类比黄河口M2分潮的无潮点，认为该海区存在一个退化到岸上的M2无潮点是可能的。

T he characteristics of the tide and the tidal current at three stations to the east of Jiazi are studied based on measurments from April to July ,2004 and methods of harmonic analysis and rotary spectrum . Results show that :1) The typical diurnal tide formed at Jiazi port and its east waters is due to the ex‐sitence of M2 tidal amphidromic point and the divergence of the tidal energy in the waters off Jiazi ;2) Al‐though the tide is dirnal ,the tidal current is regular semidiurnal ;3)Tidal wave in the concerned area is rel‐atively complicated where the characteristic of progressive wave properties is more obvious than that of standing wave;4)In analogy with the M2 tidal amphidromic point in Yellow River mouth ,a M2 tidal am‐phidromic point degenerated on land is considered possible there .
